they are verbatim 8x dvd-r and using a brand new sony d22dw dvd rewriter.

they work in my mates logix dvd player, they work in my panasonic dvd player but not my other mates sanyo one - well i say i deosnt - it gets about a 1/3 way through then locks up and the only way of restartiong it is to switch the power off and back on. even if u go to a scene after the point of lockup it wont play.

ill try buring at 4x then and see how it goes. cheers.
